Laser marking machines use laser beams to mark permanent marks on the surfaces of various materials. The effect of marking is to expose the deep material through the evaporation of the surface material, thereby engraving exquisite patterns, trademarks and texts. In the Chinese laser industry, practitioners have made specific descriptions and classifications of it. After the enterprise customers state their requirements, they can recommend the selection of appropriate models according to the actual development situation.

A. Classification of commonly used laser marking machines:

1. Fiber laser marking machine:

The main technology is used to mark the required text, patterns, barcodes and other information graphics on plastic, electronic, metal, ceramic, tobacco and other material products. The fiber laser marking machine has the advantages of simple, fast and convenient operation, fast marking speed and clearness, which continuously optimizes the production management efficiency of enterprises.

2. UV laser marking machine:

The industry used is the same as that of fiber laser marking machine, but the printed text, pattern, etc., when some fiber laser marking machines cannot engrave the required effect, the characteristics of UV laser marking machine are reflected, because UV laser marking machine belongs to the category of cold light, many products fiber laser marking machine cannot engrave satisfactory effect, UV laser marking machine can generally engrave.

3. Carbon dioxide laser marking machine:

CO2 laser marking machine uses laser beam to mark the surface of various materials in various ways. Carve out patterns, trademarks, dates, LOGO or through text. At present, CO2 laser marking machine is mainly used in some Chinese wood, paper, etc. of enterprises.

B. Advantages of laser marking machine:

1. Permanence:

For example, the mark will not fade due to environmental factors (touch, acidic and reducing gases, high temperature, low temperature, etc.).

2. Anti-counterfeiting:

The mark engraved by laser marking technology is not easy to copy and change, and has strong anti-counterfeiting to a certain extent.

3. Non-contact:

Laser marking is processed by non-mechanical "light knife", which can print marks on any regular or irregular surface, and the workpiece will not generate internal stress after marking, ensuring the original precision of the workpiece. It does not corrode the working surface, there is no "tool" wear, no toxicity, and no pollution.

4. Wide applicability:

Laser can be used as a processing method to process a variety of metals and non-metallic materials (aluminum, copper, iron, wood products, etc.).

5. High engraving accuracy:

The laser marking machine engraves fine patterns on objects, with a minimum line width of 0.04mm. The marking is clear, durable and beautiful. Laser printing can meet the needs of printing a large amount of data on extremely small plastic parts. For example, it can print two-dimensional barcodes that require more precision and higher clarity, which has stronger market competitiveness compared with embossing or jet marking.

6. Low operating cost:

The marking speed is fast and the marking is formed in one time, with low energy consumption, so the operating cost is low. Although the equipment investment of laser marking machine is larger than that of traditional marking equipment, the operating cost is much lower when using laser marking machine

7. High processing efficiency:

High processing efficiency and fast marking speed. The laser beam under computer control can move at high speed (speed up to 5-7 meters/second), and the marking process can be completed within seconds.
